Hybridisation of central atom in PCl(5) ...

Hybridisation of central atom in `PCl_(5)` involves the mixing of orbitals.

A

`s, p_(x), p_(y), d_(z^(2)), d_(x^(2)-y^(2))`

B

`s,p_(x).p_(y),p_(xy).d_(x^(2)-y^(2))`

C

`s,p_(x),p_(y),p_(z),d_(z^(2))`

D

`s,p_(x),p_(y),d_(xy),d_(z^(2))`

Text Solution

Verified by Experts

The correct Answer is:
c
The hybridization of the central atom can be calculated by the sum of sigma bond formed and the number of lone pair. In P, there are 5 valence electron in which all the 5 electrons are bonding with 5F atoms forming 5 sigma bonds. Therefore the steric number 5 denotes `sp^(3)d` hybridization in which three hybrid orbitals are equatorial and two are in axial direction.

What is a central atom or ion?

Assertion (A): Covalent radius is always shorter than the actual atomic radius. Reason (R): The formation of covalent bond involves the overlapping of atomic orbitals and it reduces the expected internuclear distance.
